Hi All,

I am using Elasticsearch 5.1.1 .  
I am trying to post data to ES as follows:

POST [http://localhost:9200/test54/data/1](http://localhost:9200/test54/data/1)

{  
"name":"data \"  
}

I am expecting "data " to be stored , However "data \" is stored as it is. i.e ES is not considering "" as a escape character.  
Note: I am **not** using any special mapping for this.  
Can someone please help ?

How did you verify that?
